Previous studies have highlighted sub-lethal effects, including inflammatory, immune, and metabolic disorders, in organisms such as algae, zooplankton, fish, and mice, as a consequence of exposure to microplastics. This serves as an early warning, signaling potential health risks for humans associated with the ingestion of plastic particles, as they have the capacity to harm human systems and disrupt normal metabolic processes [2].<\/p>\n\n\n\n<p>The goal of this project is to design textured paper surfaces for use as single-use medical waste, replacing plastic. Specifically, it aims to create a novel coating system using cellulose nanofibril paper as an alternative to plastic. By optimizing the coating process, the goal is to achieve suitable O2 permeability, water vapor permeability, and air permeability. Preliminary research has identified various coating process variables that influence the final properties, including paper basis weight, CMC content, kaolin content, post-processing time, and oven drying conditions. Given the potentially vast design space, the project aims to develop <strong>machine learning algorithms<\/strong> to aid in the search for optimal processing conditions that result in a high-performance coating. <strong>Experimental<\/strong> and <strong>simulation<\/strong> data will be utilized to train the machine learning algorithm. Once trained, the developed models will assist in understanding the underlying physical and chemical principles governing the coating&#8217;s properties and identifying optimal conditions for processing coatings with desirable properties.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"525\" height=\"157\" src=\"https:\/\/umaine.edu\/medicine\/wp-content\/uploads\/sites\/483\/2024\/11\/image.png\" alt=\"\" class=\"wp-image-47999\" style=\"width:452px;height:auto\" srcset=\"https:\/\/umaine.edu\/medicine\/wp-content\/uploads\/sites\/483\/2024\/11\/image.png 525w, https:\/\/umaine.edu\/medicine\/wp-content\/uploads\/sites\/483\/2024\/11\/image-300x90.png 300w, https:\/\/umaine.edu\/medicine\/wp-content\/uploads\/sites\/483\/2024\/11\/image-105x31.png 105w, https:\/\/umaine.edu\/medicine\/wp-content\/uploads\/sites\/483\/2024\/11\/image-317x95.png 317w, https:\/\/umaine.edu\/medicine\/wp-content\/uploads\/sites\/483\/2024\/11\/image-423x126.png 423w\" sizes=\"auto, (max-width: 320px) 85vw, (max-width: 768px) 67vw, (max-width: 1024px) 62vw,525px\" \/><\/figure><\/div>\n\n\n<p class=\"has-text-align-center\">Vacuum coating method<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"968\" height=\"375\" src=\"https:\/\/umaine.edu\/medicine\/wp-content\/uploads\/sites\/483\/2024\/11\/image-1.png\" alt=\"\" class=\"wp-image-48000\" style=\"width:607px;height:auto\" srcset=\"https:\/\/umaine.edu\/medicine\/wp-content\/uploads\/sites\/483\/2024\/11\/image-1.png 968w, https:\/\/umaine.edu\/medicine\/wp-content\/uploads\/sites\/483\/2024\/11\/image-1-300x116.png 300w, https:\/\/umaine.edu\/medicine\/wp-content\/uploads\/sites\/483\/2024\/11\/image-1-768x298.png 768w, https:\/\/umaine.edu\/medicine\/wp-content\/uploads\/sites\/483\/2024\/11\/image-1-105x41.png 105w, https:\/\/umaine.edu\/medicine\/wp-content\/uploads\/sites\/483\/2024\/11\/image-1-317x123.png 317w, https:\/\/umaine.edu\/medicine\/wp-content\/uploads\/sites\/483\/2024\/11\/image-1-423x164.png 423w, https:\/\/umaine.edu\/medicine\/wp-content\/uploads\/sites\/483\/2024\/11\/image-1-634x246.png 634w, https:\/\/umaine.edu\/medicine\/wp-content\/uploads\/sites\/483\/2024\/11\/image-1-846x328.png 846w, https:\/\/umaine.edu\/medicine\/wp-content\/uploads\/sites\/483\/2024\/11\/image-1-951x368.png 951w\" sizes=\"auto, (max-width: 320px) 85vw, (max-width: 768px) 67vw, (max-width: 1024px) 62vw,968px\" \/><\/figure><\/div>\n\n\n<p class=\"has-text-align-center\">Research framework<\/p>\n\n\n\n<p>As part of our inaugural cohort for the BRAIN (Biomedical Research and AI Nexus) initiative, two undergraduate computer science students\u2014Bradan Craig, a junior, and John Quinn, a freshman\u2014are contributing to the software development of the project. Their work includes generating training data and building advanced machine learning models to explore the relationship between processing parameters and the resulting properties of the coated surfaces. Additionally, PhD student Sandro Zier and junior undergraduate Zech Hoeft are focusing on hardware development, aiming to construct a lab-scale system for the coating process.
